Remove the paragraph with the FSF address from all the comedi source
files.
Also, remove the paragraph about the finding the complete GPL in the
COPYING file since it's unnecessary.

All the comedi drivers have been converted to use the request_firmware()
hotplug interface. The COMEDI_DEVCONFIG ioctl support for passing the
firmware blob as 'aux_data' is no longer required.
Remove the feature and give the user a dev_warn message if it is
attempted.

The 'addi_apci_1032' driver recently started supporting the
`INSN_CONFIG_DIGITAL_TRIG` configuration instruction, but as no other
drivers were using it before, there was no existing practice of how the
instruction should look.
Define the format to be something a bit more configurable. In
particular, a subdevice might have more than one trigger requiring an ID
and/or `COMEDI_EV_...` flags to disambiguate them, a trigger might have
more than 32 inputs, and a trigger might need several
`INSN_CONFIG_DIGITAL_TRIG` configuration instructions to configure
completely (if there are more than 32 inputs or if it uses a combination
of edge-triggered and level-triggered inputs).

The 'chanlist' is passed to the kernel from user space with the
COMEDI_CMD and COMEDI_CMDTEST ioctls. The do_cmd_ioctl() and
do_cmdtest_ioctl() functions in comedi_fops.c copy this data
to/from user space to kernel space correctly.
Unfortunately, this data is copied back into a struct comedi_cmd
so when the cmd is passed down to the drivers they still see the
pointer as __user data. This results is a number of sparse errors
such as:
warning: dereference of noderef expression
warning: incorrect type in argument 2 (different address spaces)
expected void const *<noident>
got unsigned int [noderef] <asn:1>*chanlist
warning: incorrect type in argument 3 (different address spaces)
expected unsigned int *chanlist
got unsigned int [noderef] <asn:1>*chanlist
warning: incorrect type in assignment (different address spaces)
expected unsigned int *ai_chanlist
got unsigned int [noderef] <asn:1>*chanlist
The two functions in comedi_fops are the only ones that need the
__user tag. Remove the tag so that all the drivers see the chanlist
pointer in the correct address space.

Hm, what a mess. I tried to properly mark up the __user pointers,
but for some of these structures, we use them both in the kernel,
and across the user/kernel boundry, which isn't ok. So we end
up generating a few new sparse warnings in places we were not before,
but the large majority of things are now properly tagged in the fops
file.
The whole ioctl interface needs to be carefully looked at in the future.

However, this flag is important to wake up the data-reader (and writer)

This adds the Comedi core to the staging tree.
This is a data acquision infrastructure for Linux, providing a common
interface for these types of drivers.
Taken directly from the comedi git tree, with only minor tweaks
by Greg to get it to build properly within the kernel tree.
